Not everyone agrees, including Mohamed El-Erian, Allianz’s chief economic adviser. He told CNBC on Wednesday that he didn’t think governments would allow the massive adoption that traders have priced in. Bitcoin should be worth “at least half” of its current price, he said.

Gundlach spoke a few hours after Jamie Dimon, JPMorgan’s CEO, said he would fire any trader who was transacting bitcoin. Bitcoin is “worse than tulip bulbs,” Dimon said, referring to the infamous speculative market for tulips in 17th-century Europe.

“It’s interesting that somebody that high-profile is out there with such an interesting statement,” Gundlach said about Dimon.
